de la Rosa ends Portimao test on top.

Pedro de la Rosa goes quickest for McLaren-Mercedes in testing at Portimao.

The 2008 Formula 1 Drivers' and Constructors' Champions McLaren-Mercedes and Ferrari brought their year to an end with a final day of testing around the new Portimao circuit in Portugal.

Only two drivers were present today with Pedro de la Rosa assuming McLaren duties and Luca Badoer getting sole responsibility with the Ferrari.

de la Rosa was the quickest of the two drivers round the undulating Algarve circuit, the McLaren team working on the interim car, complete with the KERS device that will appear in 2009. His best lap of 1min 28.998 was just over a second quicker than that of Badoer.
